杰克Lavey: 在FloSports, we're in a lucky position where we get to do everything from really low-end--I say low-end, 但基本上, 我们必须非常便宜, because we're servicing a small audience--to very high-end stuff. The high-end stuff you can't be as risky, 在我看来, ndi仍然是一件有风险的事情, 这取决于你如何使用它.
One of the things that makes NDI so interesting on the low-end is when NewTek brought out the NDI|HX Spark. The Spark converted the NDI signal to something that's only 8Mbps inside of an IP network. 当我谈到IP网络时, I'm talking about ethernet-connected, 也许是无线网络连接, maybe you're running fiber for your internet. 它非常灵活. 你可以做任何事. The biggest problem you have is most of the devices you have are only going to be capable of up to 1000 megabits on a regular gig network.
So, 1,000 megabits with full NDI core signals, typically a full NDI core signal out of this or OBS or anything is going to be a full 100 megs. That means you can only fit 10 signals on a network going into your computer or whatever your main source is.
但, with the NDI | HX being able to compress everything down to eight megabits, I can fit a ton of those on my network. At 8 megabits I can put that over WI-Fi network. I could put it over maybe a point to point network. 正确的? So, where now something that might have only been able to do 150 megs with a wireless system I can now send a ton of video signals over that. 授予, maybe there's going to be some inherent latency, maybe there's going to be some jitter, but if you're in a place where you can be a little more risky, and a lot of places where we're at we can be a little risky with what we do. It gives me the ability to do things way cheaper, and have way more of an advantage versus if I had to run an SDI cable and fiber.
For instance, if I do softball, I've got to run fiber for all my softball cameras. 但, maybe it's a low-end softball tournament, and so instead of doing that I'm going to do ethernet, because with ethernet I don't mind if it breaks. 但 my fiber cable is $3,000 a pop. 我不想把它们弄坏. So, being able to have that flexibility to go over fiber or ethernet or even maybe a wireless network is huge for what we do. 但 then also to be able to mix in different protocols into that ethernet network.
So, for instance, let's say we do marching band. With marching band I've got to get audio from the field up to the press box along with cameras. 以你现在的方式做事, you've got to run fiber down there for maybe your camera, but then you've got to run big XLR snakes up to the top. 与以太网, 我可以把丹特的声音放进去, 我可以把相机调到NDI, I can run one fiber signal down there, and I can convert everything over an IP network. So, we can put all of our 信息 on one cable.
